Features of formation of residual stresses in surface layers and coatings

Key Points

• Lower compressive residual stresses were found in multilayer magnetron coatings than in monolayer coatings, highlighting their structural differences.
• Multilayer Nb / Mo coatings exhibit residual stresses of less than 600 MPa, significantly lower than equivalent monolayer coatings.
• An original technique using elastic anisotropy allows for the analysis of residual stresses in diverse metal coatings and alloys.
• This assessment of surface layers emphasizes the importance of coating type in determining material performance.
